Abstract

Background: This cross-sectional study aimed to explore the variation trend of renal function for healthy pregnant women at different gestational ages and aimed to establish RIs for renal function set tests according to the trimester of pregnancy.

Methods: A total of 120 healthy pregnant women and 40 healthy non-pregnant women were enrolled in this study and divided into early trimester (1 - 13 weeks of gestation, n = 40), second trimester (14 - 27 weeks of gestation, n = 40), third trimester (≥ 28 weeks of gestation, n = 40), and a non-pregnant women group (n = 40). Analytes of UA, BUN, Cr, β2-MG, Cys-C, RBP, NAG, CO2, HCY, C1q, and NGAL were measured by using the analytical systems of the Second Xiangya Hospital. The RIs were defined by using non-parametric 95% intervals.

Results: The RIs for UA, Cr, β2-MG, NAG, CO2, Hcy, and C1q were established for the first and second trimester group and the third trimester group. There were huge differences after pregnancy. The RIs for BUN were different for the 1 - 13 weeks group and the after 14 weeks group. There were significant differences for NGAL in pregnant and non-pregnant women, but not for Cys-C and RBP.

Conclusions: The RIs for renal function tests in pregnant women were established, thus providing clinical reference intervals for the clinicians.
